Splined crankset - crankpuller woes.(9 posts)

Splined crankset - crankpuller woes.Eug
May 18, 2003 1:40 PM
So I was already to put on my new Ultegra 165 mm splined cranks on my bike and discovered my 105s won't come off because I don't have the right crank puller.

Is there an attachment I can get to make it work, or do I need to buy a whole new crank puller? (I have one of those Lifu complete tool kits and the crank puller works fine with my square taper MTB cranks.)

I'm thinking a penny or a dime may just work, but I'm a bit afraid I'm gonna bend the little tabs inside or something. Has anyone here done anything similar? (Dunno if canadian money is the exact same size as the US stuff.)

Oh, and while I'm at it, what is the specific bottom bracket tool I'll need if I ever decide to replace the BB?

.....leave the crankbolt dustcovers on (make sure it is as tight as it is supposed to be) and use an 8mm allen wrench, turning counter-clockwise and the crank will come off. Do the same for the non-driveside crank arm. When installing your new crank arms, remove the dust cover so you can see when the splines are lined up. Grease the crank bolt, crankbolt washer, splines, dustcover threads and inside the top of the dustcover. This will make for easier removal in the future.

Here is the Park BB tool you need if removing your splined bottom bracket:

You need to find something that has a diameter of about 5/8". Shimano does have a "gizmo" that works with a square spindle crank extractor. I think the Shimano part number is TL-FC15. It looks kind of like a top hat.

I think that Park must have discontinued the bottom bracket tool that only worked with square spindle cartridge bottom brackets. The Park part number for the tool you need is BBT-2.

Use the built in crank bolt pullers that came with your Ultegra crankset. If you don't want to do that, buy a Park CCP4 puller....................bottom bracket tool is Park BBT2

The Shimano 105 crankset does not have a self-extracting crank bolt. Use a proper crank puller from Spin Doctor or Park Tool to extract the crank arms.

If you have a Shimano Octalink splined BB, you will need a Bottom Bracket tool to remove/replace the BB cartridge.

use them to "self-extract" the 105s? Or is the bolt different?

There is a new tool, the CWP-6, that will fit both square type and Octalink (spline) type. See

For all Shimano bb's with 20 internal splines, use the BBT-2. (square or Octalink). See

Its tough to see all these posts saying just buy this or that tool, all you need is a little washer that covers the hollow axle, for your old tool to push against. Ill tell you what NOT to use, a chainring bolt washer. I thought it was pretty close to the right size but when i cranked down on it, it was pushed deep down into my bb axle, where it remains to this day. Luckily i am near a friendly shop that will yank my cranks for a freebie. I have gone right through my whole heap of parts looking for something smaller than a dime and slightly bigger that washer. good luck!

Well, I won't throw them away, but I'd rather just use the standard bolts.
